This is a free poster (right-click and Save image as...) of colourful, wonderfully crunchy chords for composing music. The double split complementaries are my favourites. I came up with them from artists' colour harmonies. They are built on C in this image, but of course you can build them on any note. If you write any music using them, I would be delighted to hear it!

You can also flip the concept upside down, use your imagination, and turn your music into art.

I do have a few hard copies of this poster on glossy A3 paper. Message me if you want one.
